With Tranquil PC's ixL you're paying a premium price for a premium product. Barring machines based on Intel's underpowered Atom processor, we can't think of another PC that runs absolutely silently and offers the potential for no moving parts, all in a small and attractive chassis. Build quality is also second to none, but the ixL's lack of a Blu-ray drive option may limit its appeal even for those who can afford it.
